Initial analysis

The 5-unit multi-family residential building at 501-505 Grove Street in Hayes Valley, owned by Mihran and Rose Trus Sagatelyan, is a 3-story flats building constructed in 1900. The property has undergone several significant renovations and improvements over the years, with the most recent major work taking place in 2020-2021, including kitchen and bathroom renovations ($49,000) with associated plumbing and electrical upgrades. Historical records show multiple deck and stair replacements attempted in 1997, though those permits expired without completion. The building has experienced various maintenance and safety issues, particularly in 2006 when multiple violations were recorded, including problems with lighting, water heaters, and general dilapidation, though these were abated by October 2006.

Recent history shows both improvements and ongoing concerns - in 2022, there were complaints about ceiling and wall cracks and rodent infestation. The building has had multiple fire safety violations in recent years, with corrected issues related to alarm systems and extinguishers in 2021-2022, and violations regarding sprinkler systems in 2019-2020. A common areas complaint was filed in November 2023 and is currently active. The property has maintained good compliance with recent building requirements, as evidenced by the completion of various modernization projects, including high-efficiency lighting installations in 2014 and 2020. While many historical issues have been resolved, the building's age and history suggest ongoing maintenance requirements are likely. The surrounding area has experienced recent municipal activity, as shown by multiple parking enforcement and street cleaning calls in 2023-2025, though these are external rather than building-specific issues.

Risk rating

How 501-505 Grove St's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.
